134 TORNATELLINA. 



It is unfortunate that the type of Tornatellina is a little- 

 known species from a peripheral locality (Juan Fernandez). 

 We know nothing of the lingual dentition or of the stages of 

 development of any species of this island. Their relations 

 to the Tornatell'inas of Polynesia and other regions remain 

 to be determined. 



If names differing from prior generic names only in gender 

 are admitted, Strobilus Anton will have priority for the 

 genus, if its type 8. twrritus, proves to be congeneric with the 

 Tornatellinas, as we suppose. It will also replace Elasmatina, 

 based upon the same species. We have not seen this species, 

 which differs from the others by its lengthened shape and 

 numerous whorls. 



The tropical American genus Leptinaria and the genus 

 Ochroderma closely resemble Tornatellina in shell characters, 

 but the dentition is Achatinoid. The species are mostly larger 

 than Tornatellina. 



Species of other families described as Tornatellina. 



Part of the species of all of the other genera of Tornatelli- 

 nidce were at first described under the generic name Torna- 

 tellina ; also the following species belonging to other families : 



Tornatellina striata Neweomb, 1861 = Leptachatina. Vol. 

 xxi, p. 62. 



Tornatellina cubeiisis Pf eiffer = Blauneria. 



Tornatellina hierosolymarum Hoih=Calaxis. Vol. xix, p. 

 285. 



Tornatellina fraseri Bs.= Ferussacia. Vol. xix, p. 249. 



Tornatellina ceylanica H. Nevill, Bnum. Helic. Ceylon, 

 1871, p. 3 ; undescribed. 



Numerous species of the genera Leptinaria and Ochroderma 

 were described as Tornatellina. See Manual, vol. xviii, pp. 

 288 to 328. 



Classification. 



Tornatellina was divided, in 1910, into four sections with 

 substantially the following characters:
